Parallel Bar Dips vs Horizontal Bar dips.

From ones perspective (like me) who trys to achieve a muscle up, doing horizontal bar dips looks more logical than doing parallel bar dips. As because horizontal bar dips look like it works the necsassary muscles for the muscle up much more. But do you think that is that right or parallel bar dips is the better way to go? Or both? I just am trying to understand their effectiveness..

these are korean dips. i just grabed this random video to show if anyone didnt know what they are. try to not swing if you can. also idk if this will help muscle ups but its another variation to try out i guess.
